Semi trucks are the backbone of the US economy, and as such, it is crucial for drivers and owners to have a reliable and long-lasting vehicle. To ensure this, semi truck manufacturers offer different types of warranties, ranging from basic to extended coverage. When deciding which semi truck has the best warranty, there are several factors to consider.
Diesel Engines: With advances in technology, diesel engines have become much more reliable than they were in the past. Many semi truck manufacturers offer extended warranties on their diesel engines that can last up to five years or 500,000 miles. Cummins and Paccar both offer five-year/500,000 mile warranties on their engines.
Transmission: Semi trucks typically come equipped with automatic transmissions that can be prone to failure over time due to wear and tear. Fortunately, many manufacturers offer extended warranties on their transmissions that can last up to seven years or 700,000 miles. Volvo offers a seven-year/700,000 mile transmission warranty for its I-Shift transmission.
Components: In addition to engine and transmission warranties, many semi truck manufacturers also offer extended warranties on components such as brakes and suspension components. Mack offers an extended six-year/750,000 mile warranty on its brake components while Freightliner offers a five-year/750,000 mile warranty on its suspensions components.
Overall:
All semi trucks provide some level of coverage in terms of basic engine and transmission warranties but when it comes down to extended coverage such as component protection or longer mileage limits – Cummins and Paccar offer the best engine coverage while Volvo provides the best transmission coverage. In terms of component protection – Mack is tops with a six year/750,000 mile warranty while Freightliner offers a five year/750,000 mile coverage for its suspensions components.
